WDF_DEVICE_INTERFACE_PROPERTY_DATA structure (wdfdevice.h)
[Applies to UMDF only]
The WDF_DEVICE_INTERFACE_PROPERTY_DATA structure describes a device interface property.
Syntax
typedef struct _WDF_DEVICE_INTERFACE_PROPERTY_DATA {
ULONG Size;
const GUID *InterfaceClassGUID;
PCUNICODE_STRING ReferenceString;
const DEVPROPKEY *PropertyKey;
LCID Lcid;
ULONG Flags;
} WDF_DEVICE_INTERFACE_PROPERTY_DATA, *PWDF_DEVICE_INTERFACE_PROPERTY_DATA;
Members
Size
The size, in bytes, of this structure.
InterfaceClassGUID
A pointer to a GUID that identifies the device interface class.
ReferenceString
A pointer to a UNICODE_STRING structure that describes a reference string for the device interface. This parameter is optional and can be NULL.
PropertyKey
A pointer to a DEVPROPKEY structure that specifies the device property key.
Lcid
Specifies a locale identifier. Set this parameter either to a language-specific LCID value or to LOCALE_NEUTRAL. The LOCALE_NEUTRAL LCID specifies that the property is language-neutral (that is, not specific to any language). Do not set this parameter to LOCALE_SYSTEM_DEFAULT or LOCALE_USER_DEFAULT. For more information about language-specific LCID values, see LCID Structure.
Flags
Not currently used. Set this member to zero.
Remarks
The WDF_DEVICE_INTERFACE_PROPERTY_DATA structure is used as input to the following methods:
- WdfDeviceAllocAndQueryInterfaceProperty
- WdfDeviceAssignInterfaceProperty
- WdfDeviceQueryInterfaceProperty
Examples
For an example of how to use WDF_DEVICE_INTERFACE_PROPERTY_DATA, see WdfDeviceAssignInterfaceProperty.
